Hi all, I am a newbie 911 engine rebuilder. I am rebuilding a '81 3.0 SC engine. I'm using Waynes rebuild book as my guide. My question concerns the torque value for the standard rod bolts. I replaced all rod bolts with new ones, followed the instructions in Waynes book for torquing ( init 20 NM, then 90 degrees more) and have them all properly torqued to this spec.
While researching other 911 info on the web, I found a porsche bulletin that states that the newer rod bolts with the 12.9 stamped in the heads have a different torque value of 15 Nm then 90 degrees. The replacement bolts I purchased are stamped with the 12.9 on the head. Does this mean that I am over torqued by 5 Nm?, Is that acceptable ?, Do I need to replace all my bolts?
Thanks for any help on this matter
